Here's an early preview of the Googlebook's extensive media editing tool

The first set of Googlebooks went up for pre-order last month and will begin shipping this Sunday. We’ve seen some apps for Google’s desktop platform land on the Play Store in the past few months, giving us an early sense of their capabilities. Another app has just arrived, and this time it’s a comprehensive media editor.

We’ve just spotted the Viewer app for Googlebooks, which will let you view or edit pictures, videos, audio files, and PDFs “all in one place.” While it only officially supports Googlebooks, we managed to try the app on one of our Android tablets, and it appears to work exactly as intended.

First-time users will see a welcome screen describing what the app does, along with a prompt to “enable timely suggestions with AI.” For instance, the AI can find a date in your content and automatically pop up a suggestion to add it to Google Calendar, and offer similar pop-ups for directions using Google Maps.

Next up, we’re taking a look at some of the image editing tools present in the app, including Annotate, Text, Resize, alongside Crop and rotate. A dedicated toolbar on the main editing page gives you instant access to these editing functions.

The PDF viewer/editor is also quite capable, with the ability to add text or annotations, and even signatures.

There’s a useful selection tool that lets you freely move or modify the text or annotations you’ve added. Like any standard PDF viewing software, Viewer shows PDF page previews on the left of the screen.

Lastly, we’re looking at the video and audio player interfaces in the screenshots above. In our testing, they appear to work as advertised, with the video player also getting an “Edit in Photos” button at the top right.

While the app isn’t really designed for slab-style Android smartphones, we were also able to sideload it and give it a spin — and it works. However, don’t be surprised if some parts of the UI are inaccessible because of display-size limitations.

If you’re considering one of the multiple Googlebooks reaching retail shelves soon, trying one of its utility apps may be the best way to get acquainted with Google’s new desktop platform. We previously dug into the platform’s Desktop Camera app and its text-editing tool, revealing some features ahead of the first Googlebooks’ arrival.
